where does our solar system end and the next begin?

Answer 1

Our solar system ends wherever the gravitational effects of the sun are too weak to hold an object in orbit. Although there is not yet solid observational evidence, The Oort cloud is a postulated spherical cloud of comets situated about 50,000 to 100,000 astronomical units from the Sun. This is approximately roughly one light year, or about 25% of the distance from the Sun to Proxima Centauri, the next nearest star. The comets of the Oort cloud are felt to be the extent of the outer solar system. Also, one light year is in agreement with measurements leading to calculations of maximal orbital effects of the Sun.

The next one begins wherever the extent of maximal orbital effects of the next nearest star take hold. This is the Centauri-A triple star system, which is slightly more massive than our Sun, and is situated more than 4.2 light-years from our Sun. It is reasonable to expect that the maximal orbital effects are out to about 1 light year from the center of this system. Therefore, there is a lot of empty space between these systems that would not be in either solar system. Bodies in that no man's land would revolve about galactic central point in the outer spiral arm of the Milky Way that we reside, without revolving around any particular star.

Answer 2

The solar system is nothing more than the system of planets and debris that revolve around our local star, the sun. Whatever revolves around our sun is part of this solar system. if it revolves around another star, it is part of a different solar system. The reach of the stars gravitational force, which differs with each star, will determine how big or small the solar system may be. Go with Jerry P 's answer, he is the man.

Answer 3

It ends at the heliopause and the next one begins at it's own heliopause.

http://en.wikipedia.org/wiki/Heliopause
"the heliopause is the boundary where the Sun's solar wind is stopped by the interstellar medium."
According to data gathered by NASA's Voyager spacecraft, the Sun's heliopause - the boundary between the solar wind and interstellar wind - seems to be approximately 23 billion kilometres from the Sun" (14 billion miles)

The nearest star, Alpha Centauri is 26 trillion miles away (that's about 2,000 times farther than the heliopause). It's heliopause is probably a similar distance.

Answer 4

Our solar system ends with the newly discovered tenth planet.
The next one begins with the nearest star.

Answer 5

All the planets orbiting around our star, conveniently named the Sun, are what defines our solar system. The next one is wherever the nearest star is, and all of the planets that orbit it.

Answer 6

Ends with the Oort Clould
When the next star system, Centari.

Answer 7

At the sign that says "leaving the milky way".
